Your answer would be 2.
Steps:
1. You add 10 and negative 8 together. You get 2.
2. You check by plugging in two.
3. It matches, so that is your answer.
Hope I helped!
Answer:
48°
Step-by-step explanation:
The sum of the three angles of a right triangle is 180°.
If one angle is 90° and another is 42°, then
90° + 42° + x = 180°
132° + x = 180°
x = 180° - 132° = 48°
The third angle is 48°.

<span>(x-4)^2 -28 = 8
</span>(x-4)^2 = 8 + 28 = 36
<span>(x-4) = +/-6
x = 6 + 4 or -6 + 4
x = 10 or -2
2.
Mistake in </span><span>Step 5: x – 3 = 16
</span><span>Step 4: (x – 3)² = 16
</span><span>Step 5: (x – 3) = +/-4
Step 6: x = 4 + 3 or -4 + 3
Step 7: x = 7 or -1
3.
</span><span>x^2 - 4x + 3 = 0
</span><span>quadratic eqn x = [-b +/- sqrt(b^2-4ac)]/2a
where in this case
a = 1, b = -4, c = 3
x = </span> [-(-4) +/- sqrt((-4)^2-4*1*3)]/2*1
= [4 +/- sqrt(16 - 12)]/2
<span>= [4 +/- sqrt(4)]/2
= [4 +/- 2]/2
= 6/2 or 2/2
= 3 or 1

Answer:
x = 13.6
Step-by-step explanation:
Here, we want to find the value of x
to find the value of x. we are going to use the sine rule
It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle
In this case;
11/ sin 27 = x/ sin 34
x = 11 sin 34/sin 27
x = 13.6
